ABSTRACT:
A photodiode having an antireflection coating for use in optical measuring devices has its antireflection coating so selected that it provides in a predetermined wavelength range an approximately constant conversion factor. The conversion of the fight power to an electrical signal is thus substantially independent of wavelength over this wavelength range.
